Hep C Vaccine discovered

The Scientist Who Discovered Hepatitis C Says He’s Now Discovered the Vaccine

By Kristen Philipkoski Feb 21, 2012 5:11 PM

In a poetic turn of virology, the scientist who discovered hepatitis C in 1989 has now also discovered a vaccine that will hopefully cure the now-incurable disease.

Not only is it poetic, it's an accomplishment that many thought was impossible. Because hepatitis C is more virulent than HIV, no one was confident a vaccine against all the various strains around the world could be developed. But Michael Houghton, the University of Alberta researcher who announced his work today at the Canada Excellence Research Chairs Summit in Vancouver, says his vaccine works against every known strain of the virus.

It could still be up to seven years before the vaccine goes through the necessary phases of clinical trials and receives FDA approval, but it's amazing news for people who thought they'd be living with hepatitis C for the rest of their lives. It also remains to be seen how much impact the vaccine will have in people who already have the disease—it will be most effective as a preventive against acquiring the disease. Hundreds of thousands of people get hepatitis C every year, and 20 to 30 per cent of them develop liver disease.

Thanks for posting that article. It certainly is encouraging that they think they now have a vaccine against Hep C.

However, there seem to be some inaccuracies or misleading statements in the article.

"the scientist who discovered hepatitis C in 1989 has now also discovered a vaccine that will hopefully cure the now-incurable disease."

"but it's amazing news for people who thought they'd be living with hepatitis C for the rest of their lives. "

Vaccines prevent diseases. They don't treat them or cure them. Hopefully a follow-up will be coming out and hopefully it will correct the inaccuracies.

However, inaccuracies aside, a vaccine is wonderful news.

Abstract

Encouraging efficacy data have been obtained in the hepatitis C virus (HCV) chimpanzee model using prophylactic vaccines comprising adjuvanted recombinant envelope gpE1/gpE2 glycoproteins or prime/boost immunization regimens using defective adenoviruses and plasmid DNA expressing non-structural genes. While usually not resulting in sterilizing immunity after experimental challenge, the progression to chronic, persistent infection (which is responsible for HCV-associated pathogenicity in human) is inhibited. These and other vaccine candidates are in clinical development for both prophylactic as well as possible therapeutic applications. Given that other vaccines tested in the chimpanzee model may be possibly increasing the rate of chronicity, it is very important that this model continues to be available and used prior to initiation of clinical development. Several vaccine monotherapy trials in chronically infected HCV patients are resulting in small declines in viral load, suggesting that in future, combining vaccination with antiviral drug treatment may be beneficial.

One learns something new every day. I could be wrong, but I think it may be a first. Regardless, it is very good news. If they have figured out a way for a vaccine to not only prevent a person from developing a disease but also to help those already infected, that is wonderful.

What a wonderful thing that would be. There was also a segment on NBC nightly news. They would like to screen boomers between the ages 45 to 65. I say keep it in the news.

This is great news.I would inoculate my family to prevent me from infecting them.

Exciting development - I'll be keeping my fingers crossed for success on this.
